I am not an expert on that by any means, but the term our lawyers use is “tax relief”. So they get some kind of tax relief in the U.K. when contributing money to the commission.
We're often approached by Canadians who might want to do the same thing, and we don't have the same status here in Canada, nor have we sought it. I think we might have checked into it many years ago, but the basic answer, as I recall, was that because we're funded by the federal government, you can't really get a tax relief for funding an institution of the federal government.
